Well, it was a bit of an idle query tbh

My interest was more in the US list, as I don't drive over there that often, so am quite out of touch with the car market.

I have a booking (group Q4) coming up at PHX, and now Ultimate Choice is live there , I just wanted to get clear in my head what groups (if any) would be equivalent or lower to Q4, so that when I get to the lot I am not totally on the back foot !
